SINK ATTACHMENT.

Patented Dec. 18, 1906.

Application filed June 6, 1906. Serial No. 320.459.

T0 aZZ whom it may concern:

Be it known that I, ANTHONY A. FIOENER, a citizen of the United States,residing at Mansfield, in the county of Richland and State of Ohio, haveinvented certain new and useful Improvements in Sink Attachments; and Ido hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

This invention relates to a drain-pipe conneotion and strainerattachment for sinks; and its objects are to simplify and improve themechanical construction and promote the sanitary condition of thedrainage of the sink, and especially to dispense with the use of screwsor bolts or similar fastenings for attaching the strainer, and toprovide simple efficient means for connecting the drainpipe andfastening the strainer in such manner as to avoid leakage and to permitready removal of the strainer for cleansing the parts. These results areattained by means substantially as hereinafter described, and moreparticularly pointed out in the appended claims, reference being made inthe description to the accompanying drawings, which form a part of thisspecification, and wherein the same reference-numerals apply tocorresponding parts in the different figures.

In said drawings, Figure 1 is a central vertical section through anattachment embodying my invention. Fig. 2 is a similar view showing amodification in the thimble or funnel, which is seated in the bell inthe bottom of the sink. Fig. 3 is a top plan view of the construction,showing half of the strainer in plan view, the remaining half of thestrainer being out oif. Figs. 4, 5, 6, and 7 are perspective views,respectively, of the strainer, thimble, bell, and tailpiece of thedrain-pipe shown arranged in position one above another for assemblingthe parts, so that the four figures show an unassembled view of theelements of the construction.

Referring for more specific explanation to the drawings, the bottom ofthe sink (not shown) is constructed either integrally or otherwise withthe usual bell, (designated by the numeral 1.) This is the ordinaryfunnellike part formed or provided in the bottom of the sink, having anupper flange or rim 2,

constituting an annular seat or depression for countersinking thestrainer. According to the usual construction the lower end of the bellis commonly united or coupled with the drain-pipe, and the strainer issecured in the bottom of the sink within the annular seat 2 by means ofscrews or bolts. In this improved construction a metal thimble orfunnel-lke part 8 sits within the bell 1, the lower end of said thimbleextending as a short exteriorly-screw-threaded tube down through thebottom of the bell to receive a nut, tube attachment, or coupling,according to the particular mode of uniting the drainpipe to saidthimble. In the present case a nickel tube or tailpiece 4 is shownscrewed on the lower end of said thimble, the said tailpiece having anupper flanged end screwed tightly against the bottom of the bell 1,making a tight connection. The thimble is seated within thefunnel-shaped or cup-shaped part of the bell below its upper rim orflange 2, and the top of said thimble is formed or provided with aninterior annular shoulder, rim, or flange 5. The strainer 6 is acircular plate, preferably of sheet metal, resting in the seat affordedby the rim 2, being thus countersunk in the bottom of the sink in theusual way, and the central apertured or reticulated portion of thestrainer, supported on or directly over the mouth of the funnel 3, ispreferably depressed or concave to lie within the mouth of the funnel orthimble, as shown. By means of lugs or tongues 7, engaging within orunder the flange 5 of the thimble the strainer is easily and securelyfastened in place. The said lugs or tongues are desirably cut from thesheet metal plate forming the strainer and are bent down to engage underthe shoulder 5, so that in fastening or unfastening the strainer itssaid lugs or tongues snap past and engage with or disengage from theshoulder. Besides being a nice mechanical construction, very simple andefficient, this arrangement obviates the use of screws or bolts forfastening the strainer, thus doing away with holes in the bottom of thesink for receiving such bolts, screws, or other fastenings. The strainercan be readily removed simply by lifting it out, sov that the outlet atthis part of the sink can be more easily accessible for cleaning and forkeeping the drainage in sanitary condition. Afurther advantage is thatwhen the sink is put in place by the workman it is a simple matter toconnect it with the drainpipe, and there is no danger of any leakage byreason of absence of bolt-holes in the bottom of the sink. With thisimprovement there is no obstruction to the free drainage of the sink.

It is understood that the bell 1 may be manufactured as a separate partfor screwing in the bottom of the sink, or the said bell may beintegrally cast or formed with the bottom of the sink, in which case itsflange or rim portion 2 would simply be an annular seat or countersinkin the bottom of the sink, and the following claims are to be construedwith the foregoing in mind. The thimble or funnel 3 is preferably madesolidthat is, with solid walls-as shown in Fig. 1 and in Fig. 5; but, ifpreferred, said thimble may be formed with slots or openings therein, asshown in Fig. 2. These and other modifications as to details may be madewithin the scope of the invention.

The construction described, while more particularly designed for sinks,may also be applicable to tubes, tanks, and basins, and in such case asuitable plug would be provided for closing the strainer when desiringto close the outlet.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent of the United States, is

1. In a drainage construction for sinks, the combination of a bellforming or adapted to form a part of the bottom of the sink, a thimbleor funnel seated in said bell, and adapted for connection with thedrain-pipe, and a strainer seated over or upon the bell and havingdepending lugs engaging the bell interiorly.

2. In a drainage construction for sinks, the combination of a bell, athimble or funnel seated therein, said thimble having an interiorshoulder within its mouth or upper portion, and a strainer seated overthe mouth of the thimble and having bottom lugs engaging said interiorshoulder.

3. In a sink attachment, the combination of a bell, a thimble or funnelseated therein having its lower end protruding below the bell andadapted for connection with the drain-pipe, said thimble having aninterior annular shoulder within its mouth or upper portion, and asheet-metal strainer seated over the thimble and having tongues or lugscut and bent down from itself and engaging under said shoulder, saidtongues or lugs being adapted to snap past said shoulder to engage withor disengage therefrom.

l. In a sink attachment, the combination of a bell having an upper rimaround its mouth constituting an annular seat for countersinking astrainer in the bottom of the sink, a thimble or funnel seated in saidbell having an upper interior annular shoulder, and a sheet-metalstrainer resting in said annular seat and having tongues or lugs cutfrom the sheet metal and bent down to engage under said shoulder, saidtongues or lugs being adapted to snap past said shoulder to engage withor disengage therefrom.

In testimony whereof I afIiX my signature in presence of two witnesses.
